All files become "read only" with self compiled plugin

Somebody else reported something similar recently - like yesterday.

BUG? Rhino 8.5 Opening ScriptEditor switches the file to ReadOnly

Following the update to Version 8.5.24051.15001, opening the ScriptEditor switches the open file to ReadOnly mode. This prevents the file from being saved, prompting the user to “Save As”. This only affects the currently open file when the ScriptEditor is opened. After saving to a newly-named file, saving is possible again. However, as long as Rhino is open, the original ReadOnly file is unable to be deleted, giving the warning “The action can’t be completed because the file is open in Python.”…

I think this may be the same problem.
